Dave - I assume that you mean n-1 or n-2 buttons on the front panel of
the Omni. I had similar issues with my TenTec filters. With 250Hz
selected on the main filter, if I selected 250Hz on n-2 (I assume that
this is what you are doing) I had significant signal loss even with the
jumpers in their proper position. I ended up adding an amplifier stage
post filter to get the gain balance correct.
When I replaced that second 250Hz filter with an Inrad filter the gain
balance was right on the money and the amplifier stage was removed. My
assumption was poor passband matching between the two TenTec filters was
the problem.

Anyone have tight CW filters in their Omni VI+ ??
I'd have to pop the bottom cover to see exactly what I have, but I know I
loaded it up with
tight CW options.
If I listen to a S9 +10db signal on 250hz, and press F1, the signal strength
stays the same.
If however, I press F2, the signal drops to about S5.
Could there be a mistake in the insertion of the filter, or what might I check
If I flip it over and look inside there?
Thanks for any thoughts on this.
